As a student, Sibelius composed several works for string quartet. In 1885 he finished a string quartet in E-flat major, followed in 1889, after quite a few individual movements for this combination, by a string quartet in A minor. The first string quartet to receive an opus number was in 1890 the quartet Op. 4 in B-flat major. Afterwards he wrote no string quartets until Voces intimae in 1909. Composed between his Third and Fourth Symphony, it remained "the only major work for string quartet of Sibelius's mature period".
